Deck Crane · Deck Cranes
The Kongsberg Maritime AS Vessel Tensioner is a deck handling tensioner used to control line, cable or product tension during offshore or specialist vessel operations. It is normally installed on an exposed working deck as part of a larger handling system with winches, sheaves, storage equipment, hydraulic or electric drives and control stations. The equipment applies controlled traction or restraint so the handled line can be paid out, recovered or held under managed tension. Its safe operation depends on sound gripping elements, bearings, drive components, structural foundations, guards, brakes and control interlocks. This tensioner differs from a conventional deck crane because its primary function is controlled linear handling rather than suspended-load lifting. The exact line type, allowable tension, drive arrangement and operational limits must be taken from the manufacturer and vessel documentation.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect foundations, welds, guards, brakes, drums or chain wheels, bearings, gearboxes, hydraulic hoses or electrical drives and all line-contact surfaces. Look for corrosion, leakage, abnormal wear, damaged fasteners and evidence of overload or line misalignment. Function-test brakes, emergency stops, local and remote controls, limits and interlocks using the approved procedure. Survey attention includes structural integrity, safe guarding, brake holding condition, maintenance records and the condition of associated wires, chains or ropes. Refer to the manufacturer documentation for exact allowable wear, test loads and adjustment values.
Useful spares include brake lining or friction components, hydraulic seals and hoses where fitted, filters, bearings, lubrication items, sensors, limit switches, contactors or control relays and common gaskets or O-rings. Load-bearing, gearbox and line-contact spares must be selected from the exact equipment drawings and manufacturer parts list.
